Are you opposed to dynamically linked libraries in general? Or do you simply oppose using them for name resolution? And how would you propose implementing NIS, LDAP/Kerberos, etc. without them (and without recompiling the libc itself)?

Valid criticism. But that's not the GNU peoples' fault, IMHO - I mean, they have a working libc, it's not their fault that containers don't work with other libcs. (Or do i misunderstand you?)
